Dry air has been pouring into South Florida this afternoon as this water vapor Gulf of Mexico satellite image shows. The radar was clear and the dew point shot down to 62 degrees at Palm Beach International Airport by 3 p.m. — with relative humidity of 49 percent.

Conditions were a little muggier in Palm Beach with a dew point of 69 and a relative humidity of 64 percent. But even at the beach the temperature was a pleasant 82. At the Lake Worth Pier, the water temperature was 82 with an air temperature of 80 and a dew point of 64.

Expect winds to start cranking up out of the northeast on Sunday, the National Weather Service said, with gusts of up to 24 mph and 34 mph on Monday.

Forecasters warned of "strong and dangerous rip currents" Sunday and through early next week, with breaking waves as high as 6 feet that could cause beach erosion and tidal flooding.

The high winds are due to a pressure gradient between a strong high pressure system to the north and an area of low pressure in the Caribbean.

The Caribbean low was whipping up showers and thunderstorms southeast of Mexico’s Yucatan Peninsula and was on a track that could take it west-northwest across the peninsula and into the Gulf of Mexico on Sunday or Monday.

Forecasters at the National Hurricane Center gave the low a 20 percent chance of becoming a tropical depression — or Tropical Storm Kate — over the next two to five days.

The low was designated Invest 92L by the NHC. Some forecast models show it heading toward the Pacific coast while others suggest it may slide up through the extreme western Gulf of Mexico.
